I was considering the idea of the Superior Implement Training when I realized nowhere that I can find specifies something in particular about a Superior Implement of Ki Focus when used as a weapon (I did find one though for just a Ki Focus used as a weapon).

If we use the example Iron Ki Focus, would the Deadly property work on a longsword with a weapon attack (Such as Melee Basic Attack) or would that fall in line with the implement power usage?
